NEW QUESTION # 270
In the SD-WAN Solution, which routing protocols can be used by LAN-side devices to connect to a Layer 3 network?
Answer: A,B,C,D
Explanation:
In the Huawei SD-WAN solution, LAN-side devices (such as CPEs and aggregation routers) use various routing protocols to connect to Layer 3 networks and exchange routes dynamically. The supported protocols include:
✅ A. IS-IS (Intermediate System to Intermediate System)
A link-state protocol often used in large enterprise networks for fast convergence and scalability.
✅ B. OSPF (Open Shortest Path First)
A widely used dynamic routing protocol for intra-domain (LAN) connectivity.
Commonly used in enterprise networks to connect SD-WAN edge routers to LAN networks.
✅ C. BGP (Border Gateway Protocol)
BGP is primarily used for WAN and internet connectivity, but it can also be used inside large enterprise networks for LAN-side routing.
BGP enables inter-domain routing and policy-based route control.
✅ D. RIP (Routing Information Protocol)
A legacy distance-vector protocol still supported in some networks for basic LAN routing.
Less preferred due to slow convergence and hop-count limitations.

NEW QUESTION # 271
In a scenario where a VXLAN tunnel is dynamically established through BGP EVPN, which of the following command needs to be run on the VBDIF interface to enable the VTEP peer to generate BGP EVPN Type 2 routes based on ARP information of the local terminal?
Answer: D
Explanation:
BGP EVPN Type 2 Route (MAC/IP Advertisement Route)
This route carries MAC and IP address bindings to inform remote VTEPs about locally learned endpoints.
Why Use arp collect host enable?
Collects ARP entries of locally connected hosts.
Enables BGP EVPN Type 2 route generation to distribute the learned ARP information.
Incorrect Answer Explanations:❌ A. mac-address xxxx-xxxx-xxxx - Manually configures a MAC address but does not enable ARP collection for EVPN Type 2 routes.❌ B. arp-proxy enable - Enables ARP Proxy but does not advertise ARP information using BGP EVPN.❌ D. arp distribute-gateway enable - Used in Distributed Anycast Gateway (DAG) mode but not for collecting host ARP data.

Answer: C
NEW QUESTION # 273
Which of the following statements is incorrect about access control on small and midsize campus networks based on the Huawei CloudCampus solution?
Answer: A
Explanation:
Understanding Huawei CloudCampus Access Control
Huawei's CloudCampus solution provides centralized authentication and policy management via iMaster NCE-Campus.
# Analysis of Each Option:
# A. iMaster NCE can function as an authentication server.
* Correct: iMaster NCE includes AAA (Authentication, Authorization, and Accounting) capabilities, reducing dependency on external servers.
# B. Cloud APs support local Portal authentication.
* Incorrect: Huawei Cloud APs do NOT support local Portal authentication.
* Instead, Portal authentication is managed centrally by iMaster NCE, NOT by individual APs.
# C. iMaster NCE can function as a Portal relay device.
* Correct: It can relay authentication requests to a RADIUS or AAA server.
# D. iMaster NCE can interconnect with a third-party RADIUS server.
* Correct: It supports integration with external RADIUS authentication servers for enterprise authentication.
Real-World Application:
* Used in Wi-Fi 6 enterprise deployments where centralized authentication, security, and policy enforcement are needed.

NEW QUESTION # 274
Which of the following statements about DHCP snooping is incorrect?
Answer: B
Explanation:
Comprehensive and Detailed In-Depth
The statement A is incorrect because enabling DHCP snooping in the VLAN view only takes effect on interfaces within that specific VLAN that have DHCP snooping configured. It does not automatically apply to all interfaces of the device. Each interface within the VLAN must individually be configured or marked as trusted/untrusted.
B: Correct, as DHCP snooping, when enabled globally without any additional specifications, defaults to processing DHCPv4 messages.
C: Correct, as DHCP snooping can protect against DHCP spoofing attacks by marking interfaces as trusted or untrusted.
D: Correct, enabling DHCP snooping on an interface means it will monitor all DHCP messages on that specific interface.
